PITTSBURGH - Player 65 saw more ice time than any other in Game 1, and during fleeting moments of his 26:58, even looked a little like the old Erik Karlsson.

But not nearly often enough.

The fact is, Karlsson was outplayed by Pittsburgh Penguins defenceman Kris Letang in the opening game of the Eastern Conference semi-final, just like he didn't perform at the same speed as P.K. Subban in Round 1.
